Rabbit Anti-CCK39/FITC Conjugated antibody
background:
Cholecystokinin is a brain/gut peptide. In the gut, it induces the release of pancreatic enzymes and the contraction of the gallbladder. In the brain, its physiologic role is unclear. The cholecystokinin pro-hormone is processed by endo- and exo-proteolytic cleavages. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Mar 2010]
Function:
Cholecystokinin (CCK) is one of the most important hormone regulators of the digestive process. The peptide is concentrated in the proximal small intestine (CCK cells) and is secreted into the blood in response to the ingestion of proteins and fats, where its actions include the stimulation of pancreatic secretion, the modulation of insulin output, the regulation of gastric emptying, and gallbladder contraction. In the central nervous system CCKergic fibres are widespread, being particularly abundant in the cerebral cortex. In some mesolimbic neurons projecting to the nucleus accumbens, CCK is colocalised with dopamine and it has been suggested that CCK might facilitate the function of dopamine in events such as stimulusreward associative behaviour. Secretion of CCK from the murine tumour cell line STC1 has been shown to be stimulated by pituitary adenylate cyclase activating protein (PACAP) and has raised the possibility that PACAP may function as a neuromodulator of CCK release from gut endocrine cells in vivo.
Subunit:
Binds to CCK-A receptors in the pancreas and CCK-B receptors in the brain (By similarity).
Subcellular Location:
Secreted
Post-translational modifications:
The precursor is cleaved by proteases to produce a number of active cholecystokinins.
Similarity:
Belongs to the gastrin/cholecystokinin family.
